Our Basement Waterproofing Process

Here's Exactly What We Do

First, we inspect your basement to identify exactly where water is getting in and why. We look at your foundation walls, floor joints, window wells, and drainage around your home. No guessing, no generic solutions.

Next, we explain what we found in plain English and show you the specific areas that need attention. We’ll tell you whether you need interior waterproofing, exterior foundation sealing, improved drainage, or a combination approach. You’ll know exactly what work needs to happen and why.

Then we get to work using the right materials for your specific foundation type and water problem. Whether that’s applying foundation sealers, installing drainage systems, or repairing cracks, we handle each step properly so the solution lasts. You’ll know when we’re coming, how long it takes, and what to expect during the process.

Basement waterproofing costs vary significantly based on the size of your basement, the severity of water problems, and which solutions are needed. Simple interior sealing might run $3,000-$5,000, while comprehensive exterior waterproofing with drainage improvements can range from $8,000-$15,000 or more. The key is getting an accurate assessment of what your specific situation requires. We provide detailed estimates that break down exactly what work is needed and why, so you can make an informed decision about protecting your home investment.
Massachusetts basements flood for several reasons, often in combination. Heavy spring rains and snowmelt overwhelm inadequate drainage around foundations. Freeze-thaw cycles create and expand cracks in foundation walls. High water tables, especially near rivers like the Charles, put constant pressure on foundations. Poor original waterproofing or drainage that has failed over time allows water to find its way in. Many older homes in East Watertown were built before modern waterproofing standards, making them particularly vulnerable during heavy weather events that seem to be happening more frequently.
The best approach depends on your specific water problem and foundation type. Exterior waterproofing is more comprehensive because it stops water before it reaches your foundation walls, but it requires excavation and costs more. Interior waterproofing is less expensive and can be very effective for managing water that does get through, but it doesn’t address the root cause. Many situations benefit from a combination approach. We assess factors like where water is entering, your soil conditions, accessibility around your foundation, and your budget to recommend the most effective solution for your specific circumstances.
Interior basement waterproofing typically takes 2-4 days depending on the size of your basement and scope of work needed. Exterior waterproofing takes longer, usually 5-10 days, because of excavation and the need for proper curing time for sealers and drainage systems. Weather can affect exterior work timelines. We schedule projects to minimize disruption to your daily routine and keep you informed about progress throughout the job. Most homeowners are surprised how quickly they can get back to normal use of their basement once the work is complete.
Proper waterproofing eliminates the moisture that causes musty basement odors, but existing mold and mildew may need additional treatment. Once we stop water from entering your basement, humidity levels drop significantly and new mold growth stops. However, you may need to clean or treat surfaces where mold has already established itself. We can recommend next steps for odor elimination once the waterproofing is complete. Most customers notice a dramatic improvement in air quality within a few weeks of completing waterproofing work, especially when combined with improved ventilation.
A properly waterproofed basement requires minimal ongoing maintenance, but a few simple steps help ensure long-term protection. Keep gutters clean and ensure downspouts direct water away from your foundation. Check that exterior drainage around your home continues to slope away from the house. If we installed interior drainage or sump pump systems, periodic inspection ensures they’re working properly. We provide specific maintenance guidelines based on the waterproofing solutions installed in your basement. Most systems are designed to work reliably for many years with basic upkeep that takes just a few minutes occasionally.
